Attribute Driven pointcuts

[YSutarko]

Hi.. can I know how I use this kind of pointcut? an example maybe?

Maybe this is a silly question.. but this are the only description about attribute driven pointcut, and I dont understand:

5.2.3.1.2. Attribute-driven pointcuts
An important type of static pointcut is a metadata-driven pointcut. This uses the values of metadata attributes: typically, source-level metadata.

and also I found this in the reference:

Later versions of Spring may offer support for "semantic pointcuts" as offered by JAC: for example, "all methods that change instance variables in the target object."

is it already available in the latest version? and do you have any examples on using it?

TransactionProxyFactoryBean uses an advisor that is driven by metadata pointcuts. (There's a layer of indirection there with TransactionAttributeSource, but it can be set up to use attributes.)

To implement a metadata-driven pointcut, just extend something like StaticMethodMatcherPointcut and look at the attributes on the class or interface.

There is no support for "semantic pointcuts" yet.
